Have a custom engineering question? Contact us →The AT55 uses the exact same 55-inch standard size (1209.6 × 680.4 mm) and standard VESA mounting dimensions as commercial 55" LCD panels. You can utilize existing installation brackets and infrastructure to upgrade seamlessly to a bezel-free, zero-seam direct-view LED display with no sending box required.
Traditional LED walls require a video processor and external sending boxes with specialized RJ45/Fiber cabling. AT55 integrates direct modular HDMI inputs, enabling true plug-and-play operation straight from media players, matrix switchers, or PC outputs, drastically cutting system complexity and failure points.
Choose QCOB for classrooms and meeting rooms where eye comfort, anti-glare, and ultra-low blue light are top priorities. Choose COB for high-traffic environments requiring IP65 protection, 12,000:1 contrast, and 30% common cathode energy savings. Choose MIP for ultra-high-definition spaces demanding P0.6 pitch, 2K resolution per cabinet, and 175° viewing angles.
Every AT55 unit comes with a 3-year factory warranty (extendable to 5 years), comprehensive batch-matched spare parts, full front-service maintenance access, and lifetime engineering support with 24/7 technical advisory.
